Webbwill yield a stress at the crack tip of approximately 45 GPa, which would exceed the theoretical strength of glass. By combining the equation for theoretical strength and stress at a crack tip, the following equation can be used to determine the practical strength of glass, based on flaw size; 𝜎 =√ 𝐸∙𝛾∙𝑟 𝑡 4∙𝑎∙𝑟0 Besides deflection, the beam equation describes forces and moments and can thus be used to describe stresses. For this reason, the Euler–Bernoulli beam equation is widely used in engineering, especially civil and mechanical, to determine the strength (as well as deflection) of beams under bending. Both the bending moment and the shear force cause stresses in the beam. The s… how hard is it to break someone\u0027s neck
